Does this test the alternator?

Jeff; This unit can be used to test the alternator. When connected to the battery, it tells you the voltage. If the voltage is higher when the engine is running you know that the alternator is working, and how much voltage it is producing. If the voltage stays the same as it was with the engine not running, you know that the alternator is not working.

Yes. It appears it provides a voltage reading with the engine running and with accessories off and on. There's a scale to indicate good or bad.

As previous answer said it's about currents. Alternating Current (AC) produces a magnetic field that this device detects. Vehicles only produce alternating current in the alternator BUT AC is immediately converted to Direct Current (DC). The only way to test for current in a vehicle is to use a standard multimeter.

Yes it will test for power as well as continuity just make certain to read the directions to confirm the color and sound that goes with each.

Yes. The manual indicates the following tests: AC/DC voltage & current (amps) measurement, resistance measurement (ohms), diode test, continuity test, and battery test.

I have one of this in a silverado pick up and it can handle the alternator output current.

It does not, the Tach reading is taken by the test lead from the negative side of the ignition coil.

It measures voltage and pulses/rpms on everything. I've tried it on 2 stroke snowmobile motors, 4 stroke tractor motors, car engines ect...it works on everything. I bought mine a few years ago and it still works just fine. I've been very happy with it...it does what it says it does accurately.

I am not sure but could test it for you. Are you able to have it installed so it's connected to the battery of the car? If you want to me to email you the results I can.

No. I tis designed to test off the shelf batteries. I personally have used it to test rechargables. It works on some but not on others. Have no idea why.

No it will not. The only way to clear a trouble code out of OBD-I is disconnecting the battery for a few minutes. Honestly this device does the same thing as small jumper wire from the a to b pins. ABS feature is useful if it's compatable for your vehicle, it was not on my Saturn so I returned it.

Yes, though I would not recommend it. This tester is very cheap and will just stop working after a couple of uses

not at all, BUT, you should replace the rubber pads you will discover when you remove your old alternator. I soldered the connectors rather than trust crimp ons as well.

Yes but i wouldnot use it this is a exitor alternator just use ground and hook wire to positive side ofbattery

Use a volt meter and look for a wire that only has power when the ignition is on.

No, but check the name plate, that will tell you the voltage and current draw, amps.

It is not a load tester. It does not place a load on the battery. It measures the reluctance of the battery and calculates the CCA.

Of course it will. The device doesn't see the type of vehicle it is used on only that it is being asked to supply current to the vehicle.
